Remembering the ozone layer

World Ozone Day is celebrated every year on 16th September since 1995. This Day marks the importance of the ozone layer and its role in the environment. The United Nations General Assembly has designated this Day to reflect the adoption of Montreal Protocol on substances that deplete the Ozone layer.

There are numerous activities and programs organized to spread awareness about the global phenomenon of Ozone layer depletion. All member nations of the Montreal protocol take this opportunity to take some concrete steps at their national level in accordance with the aims and objectives of Montreal protocol.

The year 2012 marked the 25th anniversary of the signing of the Montreal Protocol. Accordingly, the Montreal Protocol community organized a range of celebrations at the national, regional and international levels to publicize its considerable success to date and to consider the work ahead for the future.

Among its accomplishments:

  • The Montreal Protocol was the first international treaty to address a global environmental regulatory challenge;
  • the first to embrace the "precautionary principle" in its design for science-based policymaking;
  • the first treaty where independent experts on atmospheric science, environmental impacts, chemical technology, and economics, reported directly to Parties, without edit or censorship, functioning under norms of professionalism, peer review, and respect;
  • the first to provide for national differences in responsibility and financial capacity to respond by establishing a multilateral fund for technology transfer;
  • the first MEA with stringent reporting, trade, and binding chemical phase-out obligations for both developed and developing countries;
  • and the first treaty with a financial mechanism managed democratically by an Executive Board with equal representation by developed and developing countries.

Within 25 years of signing, Parties to the MP celebrate significant milestones; however, the job is not yet done and the current moment could not be more pivotal for accomplishing its vital mission. Significantly, the world has phased-out 98% of the Ozone-Depleting Substances (ODS) contained in nearly 100 hazardous chemicals worldwide; every country is in compliance with stringent obligations; and, the MP has achieved the status of the first global regime with universal ratification;
